seems to have matched rival Seagate's per-platter storage density mark, with its 500GB platter technology. What's more, WD is planning to release a quad-platter hard drive totaling two terabytes of unformatted capacity before Seagate could achieve that feat with its Barracuda 7200.12 series. Seagate was the first to come out with a 1.5TB hard drive with four 375GB platters.techPowerUp! News :: Western Digital Ups Platter Density, to Launch 2 TB HDD

If you plan to use the 2TB as a entire drive your going to be stuck to a few OSs that will support it because the only way to properly be able to use a 2TB drive is with an OS that can read GPT tables as MBR will no longer work.

Any system that I would put a drive like this in it, use already uses an OS that would support it, no issue.

All recent modern OSs(Mac OSX, Windows, Linux) I can think of, all support GPT tables.

Plus isn't this only true for using this as your O/S drive? The only way I'd buy anything this large would be if I were to put it in my server. I find my WD 640GB Black was way larger than I would use, as all my storage goes onto my server. I think I'd have plenty of space with 2x 64GB SSDs in RAID0 (or 4x 32GB!!)
